Abstract
The present invention relates to a new aqueous curable binder composition comprising a polyphenolic macromolecular compound which bears a multitude of catechol radicals (dihydroxybenzene), preferably lignosulfonate salts and condensed tannins and mixtures thereof, and a polyamine functional compound comprising primary and/or secondary and/or tertiary and/or quaternary amine functional groups, suitable for bonding particulate matter, such as fibers, more particularly mineral wool fibers, or particles, such as wood particles.
Claims15
An aqueous curable binder composition comprising (i) a polyphenolic macromolecular compound which bears a multitude of phenol or polyhydroxybenzene radicals, such as catechol radicals (dihydroxybenzene), preferably lignosulfonate salts and condensed tannins and mixtures thereof, and (ii) a polyamine functional compound comprising primary and/or secondary and/or tertiary and/or quaternary amine functional groups, and/or reaction product of (i) and (ii), the ratio of polyphenolic macromolecular compound to polyamine functional compound ranging from 98:2 to 50:50, preferably from 98:2 to 70:30 w %, more preferably from 95:5 to 80:20 w %.
